A 200-litre mixture contains milk and water in the ratio 3 : 2. How many litres of water must be added to make the ratio 5 : 4?
A. 16 litres✓ Correct Answer
B. 32 litres
C. 96 litres
D. 88.89 litres
💡 Solution & Explanation
Milk = 200 × 3/5 = 120 litres and water = 80 litres. Adding water does not change the milk. For milk : water = 5 : 4, the water must be 120 × 4/5 = 96 litres. So add 96 − 80 = 16 litres of water.
